oil cut, GOR question

oil cut, GOR question

oil cut, GOR question

(OP)
What does it mean when i am told a well produces 1000 barrels of total fluid with a GOR of 500 scf/bbl and 50% oil cut? with a wellhead pressure of 2000 psi at primary production?

How much oil, produces water and gas will i be producing?

does this mean 500 bbls of oil, and 500 bbls of water with 500000 scf of gaS?

RE: oil cut, GOR question

yes

RE: oil cut, GOR question

Apologies to BigInch but no.

500 bbls water + 500 bbls oil is correct but

GOR = Gas / Oil Ratio (scf/bbl)

therefore Gas flow = 500 scf/bbl x 500 bbl(oil)= 250000 scf

RE: oil cut, GOR question

You're 100% right.  1000 x 500 looked right when I got to the end of the question.  Apologies elque.

RE: oil cut, GOR question

Elq:

I would like to give one warning - it depends (a little) whether you are upstream or downstream.

The reservoir engineer will set up his simulation to produce a result such as the one you mention.

As a facility eng. you will receive

a) A composition
b) A production profile.

GOR may change over the years - but you are only issued one composition. Most chemical engineer will now realise that something doesn't add up.

Furthermore you should also ask the reservoir eng - how did you set up the simulation. The results may be based on a single flash at standard conditions - or a 4 stage flash a specified pressures and temperatures - you cant be sure until you ask and this data may not be given to you. And just because it was something the last time . its not certain its the same this time. So always ask.

Best regards

Morten
